Specification of Letters Patent.

Patented April 20, 1909.

Application filed'February 21, 1908,. Serial No. 417,107.

To all whom it may concern:

Be it known that I, DANIEL A. ivnmronn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented 5 certain Improvements in Wire Ties for Metallic Reinforces, of which the following is a specification. The object of my invention is to provide an efficient form of wire tie for use in connection with reinforcing bars or rods for concrete construction.

My invention comprises a form of tie capable of modification and particularly adapted for use in tying together the members forming reinforces for girders, beams,

posts, columns and the like.

My invention is fully shown in the ac com'panying drawings, in which:

F1gure.l, 1s a perspective viewof one form of tie embodying my invention; Fig. 2, is a perspective view showing the same in position of use; Fi 3, is a perspective view of another form of tie embodying my invention; Fig. at, is a. perspective view showing the same in the position of use; Fig. 5, is a perspective view of a modified form of the tie shown in Fig. 3; Fig. 6, is a view of still another form of tie somewhat similar to the structure shown in Fig. 1, but arranged to operate in a slightly diiferent manner, and Fig. 7, is a perspective view of the same in the position of use. i

In a companion application. filed of even date herewith, I have shown a-metallic reinforce .for concrete construction, the individual metal portions of which are secured together by means of ties of the several forms disclosed herewith. The most desirable feature in ties of this 40 character is the ability to secure them to the work on the job in a simple and efiicient manner; the tie being so constructed and arranged when in place as to prevent dis-' lodgment, and at the same time to permit movement of the members secured together with respect to each other without danger of separation due to such movement.

Referring to the drawings, Fig. 2, shows a tie connection designed for use between longitudinal reinforcing bars 1 and the uper portions 2 of the stirrup; suchmember Eein shown in the normal shape before use in *ig. 1. Itconsists of a wire member having two substantially parallel. runs 5 and t6- 5", the run 5 being longer than 5. The

runs 5 and 5 are joined by a loop 6, and said runs have hook portions 7 and 7 respectively. The loop of this .tie is caught under the bar or rod; the runs 5 and 5 are p then brought down over the stirrup projecv tion 2 by lying at right angles to said bar, and then the hooks 7 and 72 in the order named are caught underneath the bar in the manner clearly. shown in Fig. 2. This arrangement permits either member to move 6' with respect to the other, and when the members are assembled in proper relation to each other, such for instance as shown in Fig. 2, the structure may be readil collapsed. It -will be noted, however, t at in order to permit this collapsing, the longitudinal rods are disposed below the projections 2 of the stirrups; the tie members forming with the bar or rod a bearing in which the projection of the. stirrup may turn.

For use in connecting the lower cross-runs of a stirrup with the longitudinal bars, I may use a tie member of the type shown in Figs. 3 and 4, or that shown in Fig. 5. go That shown in Figs. 3 and 4, comprises a structure having a loop 8 to engage the rod, fromwhich a run 9 extends terminating in a hook 10 to engage the cross run of the stirrup. Another run 9 extends from said loop portion 8 and passes over said rod an downwardly in a long curve or loop forming a support or foot; the end of said runlbeing provided with a hook 10Pwhich is caught over the rod. The foot or support which this form of tie provides, will serve to raise the stirrup above the centering, and at' the same time obviates the necessity of using stirrups with. their upper ends in engagement with the centermg in order to ralse on them to the proper height toinsure the-required layer of concrete beneath the beam or girder. This permits the use of straight arm projections for the stirrups.

In Fig. 5, I have shown a form of tie "with. 10o two supports or feet. This may be used when the metal of the reinforce 1s particularly heavy.

In Fig. 6, I have shown another form of tie in its normal shape and in Fig. 7, in the 10:3 position of use. This tie comprises a piece of wire doubled upon itself, and like the first mentioned tie shown in Figs. 1 and 2, it has runs 12 and 12 of unequal length joined by .a loop ,13. The long run 12 is provided'with a hook 14 lyingin the plane of the loop 13 connecting the runs, while the short run 12 is provided with a hook 1 4 lying in a plane at right angles to the hook 11. In the manner of attachin it to reinforcing rods which cross eac other as shown in the drawings, the hook 1 1' may engage the horizontal rods, while the hook 14 may engage the vertical rods. Such arof ties capable of performing the f unction ranged desired in structures of this charactermay be employed with equal facility, and my in vention is not limited to the use of any specific form of tie or those shown herein.

I claim:

'1. A wire tie for securing metallic members in contact with each other at their crossing points and permitting hinged movement of either member withv respect to the other, said tie having a loop to be enaged by one of said members, runs aralcling said loop-engaged member a arto engage-and pass over the other member, and hooks carried b said runs for locking the tie to said metal ic members.

A wire tie for securing a plurality of crossing rods at an angle in contact with each other, said tie having a loop to be engaged by one of said rods runs paralleling said 100' engaged rod and arranged to engage an pass over the other rod, and hooks carried by said runs for engagement with the rods.

3. A wire tie for securing metallic members in contact with each other at their membcr and arranged to engage an said rods, and hooks carried by either one may turn within the tie with respect to the other.

5. A wire tie forsecuring crossing rods in contact with each other at their point of intersection, said tie having a 100 to be engaged b one of said rods, runs integral with said 00p and terminating in hooks for engagement with said rods whereby they are held together. so that either one may turn within the tieewith respect to the other, and a su port formed by one of said runs between t e hooked portions of the same.

6. The combination of a pair of metallic members crossing each other at an angle, and a wire tie for securing said members in;

contact with each other at their crossin point and permitting hinged movement o either with respect to the other, said tie having a loop to'be engagedrby one of said members, runs paralleling said loop-enigagd pass over the other member, and hooks carried by said runs for locking the tie to said metallic members.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
